STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 424,735, dated April 1,1890.

Application filed September 16, 1889. Serial No. 324,130. (No model.)

To @ZZ whom it may concern:

Beit known that l, WILLIAM 1I. SMITH, a citizen of the United States,residing at Chicago, in the county of Cook. and State of Illinois, haveinvented new and useful Improvements in Steam-Boilers; and I do herebydeclare the following to be a full, clear, and exact description of saidinvention, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in steam-boilers, and moreparticularly to that class known as water-tube boilers.

The object of my invention is to support the battery of wateiet-ubes inwhich the wat-er is heated and generated into steam from suitablesupports independent of the stearnalrliln, and also to provide a saddlewhich connects with the headers of the water-tubes and with thesteam-drum, and by which the battery of water-tubes is supported.

The invention consists, first, in supporting the water-tubes orheader-sections from a cross beam or support through rods, and also thesteanrdrum.

It further consists in connecting the front end of the battery ofwater-tubes with a saddle supported by rods connected with cross beams,and in supporting the steam-drum in the saddle to communicate with thebattery of water-tubes, whereby thel weight of the tubes is supportedwholly from the beams, as also the steam-drum.

The invention further consists in t-he saddle supported by thecross-beams, having the several headers connected therewith and forminga communicating passageway between the headers and steam-drum6 Itfurther consists in a novel manner of supporting the rear end of thebattery of water-tubes.

It further consists in certain novel features in the construction andarrangement of parts, all as hereinafter explained.

In the accompanying drawings, Figure l is a front view of a boiler,partly in section, showing the saddle to which the headers areconnected, and the front erossbeam, and the rods for supporting thesaddle. 2 is a rear elevation showing a similar manner of supporting therear ends of the tubes. Fig.

3 is a longitudinal sect-ion through the casing, showing the water-tubesand steam-drum in full lines. Fig. a is a rear view showing the upperand lower saddles and the means of connecting the same together and withthe header.

The headers or sections A are made in polygonal form, with the severalsides of one section abutting against and connected to others of theseries, the connection being made by means of wrought-iron or steelnipples c expanded between them, by which it will be seen that each oneof the series is connected at the top and bottom, and at its oppositeparallel sides another one of the series, and at each of its fourangular sides with another of the series, both ends being constructed ina similar manner and having the tubes connected to each section in asimilar manner to boilers provided with headers in common use.

To a cross-beam B, support-ed at each end upon a column B', areconnected depending rods B", to the lower ends of which are connected.in any suitable manner a saddle or support B", having angular andparallel faces corresponding to the shape of the upper and lowerheaders, and to which saddle said headers are connected in a similarmanner as to each other. This saddle is made in hollow form, with itsupper face concave or formed on the arc of a circle corresponding to thediameter of the steam-drum, and in which concave portion the steam-drumD rests. The drum is cut away at the point over the hollow saddle, andthe drinn and saddle are connected through a steam-tight joint, and fromwhich it will be seen that the battery of water-tubes is supportedentirely independent of the steam-drum. It will also be seen that thesaddle forms a connecting passageway between the several sections of theheaders and the steam-drum. The headers at the rear end are connectedtogether in a similar manner to those at the front, and a saddle is alsoemployed to support the steamdrum at the rear end; but in. this case thesaddle, which is connected directly to the cross-beam, is provided witha series of dedepending circulating pipes or tubes C, having at theirlower end. a similar saddle C', which in this case is provided withangular and upper and lower parallel faces Corre- IOO Having thusdescribed my invention, what I claim, and desire to secure by LettersPatent, 1s-

1. In a steam-boiler, the Watertubes, theA cross-beam or support, therods connected to the Water-tubes to support the tubes orheadersections, and the steam-drum, also supported by the rods,substantially as described.

2. The battery of watertubes, having its front end supported by asaddle, the crossbeam, and rods connecting the cross-bealn With thesaddle, and the steam-drum supported by the saddleto communicate withthe headers of the Water-tubes through the saddle, substantially asdescribed.

3. The saddle supported by the cross-beam, having the several headersconnected therewith and forming a communicating passage-y Way betweentheheaders and the steain-dru 1n, substantially as described.

6. The header-section provided with opposite parallel side faces havingopenings therein, and a mud-drum having corresponding matching faces,provided with openings communicating with the header-section throughboth .the vertical and parallelsides, substantially as described. Y
